Technology overview

Introduction

A wide variety of granular processes can be examined using numerical simulation. Recent advances in numerical algorithms and the continual increase in performance of computer systems now enables the simulation of large-scale industrial particulate (granular and powder) processes.

Simulation techniques

Granulair Technologies employs two different state-of-the-art numerical simulation technologies: DEM (Discrete Element Method) and CFD (Computational Fluid Dynamics). These simulation techniques are used to cover a wide spectrum of applications.
